10T Unicorn Bag for Mushroom Spawn Production

If you’re producing your own grain spawn to a reasonable scale, then you’ve most likely moved on from the mason-jar-and-drilled-lid end of things, and you need something more substantial, and easier to store - once again we’ve got the goods - Unicorn Bags!

Like we said on the Microppose Adhesive Tub Filter page, there are a few companies that are absolute leaders in the world of mushroom cultivation, and Unicorn are one of the big daddies. Based over in sunny Texas, they make a whole range of sturdy bags purpose-designed for one thing: growing loads of mushrooms. They’ve been going since 1990, so really if you wanna double-down on a crazy niche then after 30+ years you’d be fairly sure there’s not much about making mushroom spawn bags that they don’t know. 

Obviously them being all the way over there in Cowboyland makes it a bit tricky if you just want to buy a few bags for your home grows, so that’s where we come in useful, buying pallets of them, shipping them over here, and selling them in quantities of as little as ten at a time. 

Technical specs? Yeah go on then:

• Use: Spawn
• Type: Gusseted
• Material: 3.0 Mil Polypropylene
• Bag Size: 5″ X 4 X 18″
• Filter Type: T
• Filter Size: 1.5″X1.5″
• Filter Pore Size: 0.2 microns
• Filter Hole: Style L

This side-gusseted breathable bag gives a sturdy stand-up bag after filling and a strong bottom seal. We manufacture it with equipment we designed and with proprietary additives, Unicorn Bags are pliable at any temperature as well as after sterilization. The bag opening is designed for easy sealing and the bag’s bottom seal can withstand agitation.

So from my not-quite-layman’s reading of that, they’re sturdy as heck, they’ve got a breathable filter that won’t let any contaminants in, and they’ll withstand being heated up, shaken around, and some general bullying probably. Industry-leading for a reason!
